In mathematics, a half-integer is a number of the form n + \tfrac{1}{2}, where n is an integer. For example, 4\tfrac12,\quad 7/2,\quad -\tfrac{13}{2},\quad 8.5 are all half-integers. The name "half-integer" is perhaps misleading, as each integer n is itself half of the integer 2n. A name such as "integer-plus-half" may be more accurate, but while not literally true, "half integer" is the conventional term. Half-integers occur frequently enough in mathematics and in quantum mechanics that a distinct term is convenient.
